Georgia media organizations reported Friday that arrest warrants in Ben Hill County show 32-year-old Bo Dukes was charged with concealing a death, evidence tampering and hindering the apprehension of a criminal in connection with the slaying of Tara Grinstead, 30. Dukes was released from jail on bond Friday.

Grinstead went missing in October 2005. Last week, authorities announced they had arrested 33-year-old Ryan Alexander Duke and charged him with her murder. It was not immediately clear how the two suspects knew each other, but CBS affiliate WMAZ reports Bo Dukes and Ryan Alexander Duke attended Irwin County High School together, where Grinstead taught.

Earlier charges say Ryan Alexander Duke used his hands to kill Grinstead, a former beauty queen, in her Ocilla home. According to a warrant, Bo Dukes helped “conceal and destroy” Grinstead’s body at a farm in Ben Hill County sometime between Oct. 23 and Oct. 28, 2005.
